First, screen brightness is not a complicated configuration of the Windows 10 operating system When it works correctly. If your screen does not look good, that is, it is too dark. Even with the brightness set to maximum, you may need to calibrate your screen again, among other things. Similarly, you can try some things so you can fix the screen brightness.
How to fix screen brightness
Before proceeding with any correction, make sure the problem is on the screen and not in what you are seeing. You must open some different images or play some different multimedia files. Also, be sure to include live action and animated content so you are not only playing content in low light. (Like that episode of Game of Thrones).
Now, if all the media and everything you've played are too dark. Then you must try these solutions that we will present:
Verify third party applications
Similarly, if you have an application installed to modify the user interface, you should check if there is something that adds visual improvements at the operating system level. They may interfere with the brightness, or may not work properly. What makes the screen look darker. Also, check if something could have added an overlay to your screen.
Check Night Light or F.lux
First, Night Light is a feature of Windows 10 that adds an orange hue to the screen. So check if you may have activated it. If you prefer to use F.lux over the native function, verify its configuration. This does more than dye the screen orange. Disable it and see if this solves the problem.
Restart the graphics controller
First, press the keys: WIN + CTRL + SHIFT + B on your keyboard to reset the graphics controller. Your screen will flash once and the graphics controller will restart.
Screen brightness: check the graphics control panel
Screen graphics are handled by the integrated graphics card. And generally, it is an Intel chip. Now, open the Intel Graphics settings and go to the "Display" tab. Similarly, look for the color setting, or something similar.
Normally, the brightness control in Windows 10 and the brightness buttons on your keyboard have the highest level of control over the brightness of your screen. But this application could interfere with it. Make sure the brightness is set to its highest value in the application too.
Uninstall and reinstall the graphics driver
It is better to do this in safe mode, since it runs in a low graphics mode by default. Open Device Manager and look for "Display adapters." Now, expand and right click on the integrated graphics card. Now, select "Uninstall device." Restart your PC and the graphics driver should be installed again.
Now, if they are not, you must return to the Device Manager, right-click on the integrated graphics card. And now select the installation or enablement option.
Now, in the Windows search, type the following:
calibrate color display
This will open the screen calibration application. Read the instructions that tell you how to calibrate the screen. Now, change the settings until your screen looks better, but keep in mind that you don't end up with faded colors.
Screen brightness: check the BIOS
Similarly, some laptops have a brightness control in the BIOS. On this occasion, we cannot give you a complete list of which ones have them and which do not. Nor can we tell you where to look in the BIOS. What you have to do is access the BIOS and look for the brightness settings. If you find the brightness setting, then you should make sure it is not too low.
Finally, and beyond this, it is possible that your hardware is damaged. And if the above does not help, verify that your screen has no problems.
